CROSS-REFERENCE TO RELATED PATENT APPLICATIONS

This is a continuation of application Ser. No. 14/035,589 filed Sep. 24, 2013, which claims priority from Korean Patent Application No. 10-2012-0105959, filed on Sep. 24, 2012, in the Korean Intellectual Property Office, and priority from Korean Patent Application No. 10-2013-0026809, filed on Mar. 13, 2013, in the Korean Intellectual Property Office, the disclosures of which are incorporated herein by reference in their respective entireties.

BACKGROUND

1. Technical Field

Exemplary embodiments relate to an ultrasound apparatus for providing a gain setup window for setting a gain or a list of one or more preset gains, and an information providing method which is implementable by using the ultrasound apparatus.

2. Description of the Related Art

An ultrasound diagnosis apparatus obtains an image of soft tissues or blood flow by transmitting an ultrasound signal from a body surface of an object toward a predetermined site inside the body, and receiving an ultrasound signal reflected from tissues in the body.

The ultrasound diagnosis apparatus is small, is inexpensive, and allows real time display. Further, because it does not cause an exposure to radiation and thus is safe, the ultrasound diagnosis apparatus is broadly used together with other imaging diagnosis apparatuses, such as an X-ray diagnostic apparatus, a computerized tomography (CT) scanner, a magnetic resonance image (MRI) apparatus, and a nuclear medicine diagnostic apparatus.

In general, an ultrasonic beam that propagates through tissues is reduced in amplitude or intensity as a function of a transmission distance. Attenuation occurs in a form that the amplitude reduces greatly if the transmission distance is large. Due to the attenuation, the intensity of a received echo ultrasound signal may not be uniform. In particular, an ultrasound image which is based on the echo ultrasound signal may not have a uniform brightness or may partially have a poor quality. Accordingly, a system for allowing a user to easily compensate the sensitivity of an ultrasound image is required.

A method for providing an ultrasound image and/or a gain setup window for setting a gain which is implementable by using the ultrasound apparatus 100 will now be described in detail with reference to FIG. 2.

FIG. 2 is a flowchart which illustrates an information providing method which is executable by using an ultrasound apparatus, according to an exemplary embodiment.

Referring to FIG. 2, the information providing method includes operations which are performable by using the ultrasound apparatus 100 illustrated in FIGS. 1A, 1B, and 1C. Accordingly, although not repeatedly provided, the descriptions provided above in relation to the ultrasound apparatus 100 may also be applied to the information providing method of FIG. 2.

In operation S210, the ultrasound apparatus 100 may obtain ultrasound image data which relates to an object. For example, the ultrasound apparatus 100 may transmit ultrasonic waves to the object and may generate the ultrasound image data based on an ultrasound echo signal which is received from the object.

In operation S220, the ultrasound apparatus 100 may display, on a first area of a screen, a gain setup window for setting a gain with respect to the ultrasound image data. The gain may include at least one of a time gain compensation (TGC) value and a lateral gain compensation (LGC) value.

The TGC value is a value which may be used to compensate for a reduction in intensity of an ultrasound signal based on a depth in a human body. The LGC value is a value which may be used to compensate for uneven respective differences in attenuation due to different corresponding transmission paths of ultrasonic beams. Hereinafter, for convenience of explanation, the TGC value is described as an example of the gain.

The ultrasound apparatus 100 may display, on the gain setup window, at least one slide bar for setting the gain. For example, the ultrasound apparatus 100 may align and display a plurality of slide bars on the gain setup window along a depth direction of an ultrasound image. The depth direction may refer to a direction in which a depth increases from the surface of an object to be diagnosed by using the ultrasound apparatus 100 with respect to interior soft tissues.

The slide bar refers to a GUI which is configured for enabling a user to adjust the gain at a certain depth.

The slide bars may be aligned in parallel at equal intervals along the depth direction.

When the ultrasound image data is obtained, if a gain which is set by the user does not exist, the ultrasound apparatus 100 may display, on the first area, an initial gain of the object based on the depth. In this case, the ultrasound apparatus 100 may display, on the screen, an ultrasound image which is generated by applying the initial gain.

In operation S230, the ultrasound apparatus 100 may receive the gain which is set by the user on the gain setup window. In particular, the ultrasound apparatus 100 may use the gain which is set by the user on the gain setup window.

The ultrasound apparatus 100 may sense a touch input of the user on the slide bar. The touch input may be any one or more of a drag input and/or a tap input. For example, the user may drag an adjustment button and/or tap a certain position on the slide bar.

“Drag” refers to an operation by which the user touches the screen by using a finger or a touch tool and then moves the finger or the touch tool to another position on the screen while continuously maintaining contact with the screen. “Tap” refers to an operation by which the user touches the screen by using a finger or a touch tool (e.g., an electronic pen or a stylus) and then lifts the finger or the touch tool from the screen without moving it with respect to the screen.

The ultrasound apparatus 100 may extract a gain which corresponds to a sensed position of the touch input. In particular, the ultrasound apparatus 100 may obtain the gain which is set by the user with respect to a depth represented by the slide bar.

According to another exemplary embodiment, the ultrasound apparatus 100 may sense a drag input of the user who performs the drag operation in the depth direction on the gain setup window (i.e., a direction which is perpendicular to the slide bars). The ultrasound apparatus 100 may extract individual gains which respectively correspond to depths of the ultrasound image based on positions of the drag input (e.g., coordinates of pixels where the drag input is sensed).

For example, if the user performs a drag operation on the gain setup window in a direction which is perpendicular to the slide bars along a straight line or a curved line, the ultrasound apparatus 100 may extract individual gains which respectively correspond to dragged positions and may set the gains with regard to the depths.

Based on the gains which are extracted based on the positions of the drag input, the ultrasound apparatus 100 may move and display adjustment buttons on the slide bars.

In operation S240, the ultrasound apparatus 100 may display, on a second area of the screen, an ultrasound image to which the gain set by the user on the gain setup window is applicable. For example, the ultrasound apparatus 100 may newly generate or partially change the ultrasound image of the object by applying the gain which is set by the user to the ultrasound image data.

Accordingly, the user may adjust the gain on the gain setup window while viewing the ultrasound image to which the adjusted gain is applied in real time. If the user sets a high gain, the ultrasound image may become brighter. If the user sets a low gain, the ultrasound image may become darker.

A method for receiving a set TGC value which is executable by using the ultrasound apparatus 100 will now be described in detail with reference to FIGS. 3, 4, 5, 6, and 7.

FIG. 3 is an image of a TGC setup screen 310 of the ultrasound apparatus 100, according to an exemplary embodiment.

As illustrated in FIG. 3, the ultrasound apparatus 100 may provide, on a touchscreen, the TGC setup button 310 which is used to be provided as a knob button. Accordingly, if a user touches the TGC setup button 310 on the touchscreen, the ultrasound apparatus 100 enters a TGC setup mode for enabling the user to set a TGC value.

FIG. 4 is an image of a gain setup window 410 for setting a gain, according to an exemplary embodiment.

As illustrated in FIG. 4, the ultrasound apparatus 100 may display, on a first area of a screen, the gain setup window 410 for setting a gain of ultrasound image data. In this case, the gain setup window 410 may include a plurality of slide bars for individually setting gains regarding a plurality of depths. The slide bars may be aligned in parallel in a depth direction.

The ultrasound apparatus 100 may display an ultrasound image 420 of an object on a second area of the screen. The ultrasound apparatus 100 may locate the second area where the ultrasound image 420 is displayed in relatively close proximity to the first area where the gain setup window 410 is displayed, and thus may prevent distributed attention when the user sets the TGC value.

Further, the ultrasound apparatus 100 may obtain a gain line 430 which corresponds to the gains which are set on the gain setup window 410, and may display the gain line 430 on the second area. A detailed description thereof will be provided below with reference to FIG. 6.

FIGS. 5A, 5B, and 5C are images which illustrate a screen for receiving a gain from a user, according to exemplary embodiments.

A user may set a TGC value by touching at least one slide bar and moving an adjustment button on the slide bar, or by performing a drag operation in a direction which is perpendicular to a plurality of slide bars.

As illustrated in FIG. 5A, a user may drag an adjustment button on a slide bar in a leftward direction or a rightward direction. In this case, the ultrasound apparatus 100 may sense the drag input of the user and may display the adjustment button at a position where the drag ends.

If the user drags an adjustment button on a first slide bar 510 in a leftward direction, a TGC value which corresponds to a depth which is represented by the first slide bar 510 may be reduced. In this case, a portion of an ultrasound image which corresponds to the depth represented by the first slide bar 510 may be reduced in brightness and thus may be displayed relatively dark.

A user may individually adjust respective TGC values which correspond to a plurality of depths by moving adjustment buttons on a plurality of slide bars which are allocated based on the depths.

As illustrated in FIGS. 5B and 5C, a user may simultaneously set TGC values which individually correspond to a plurality of depths by performing a drag operation on a gain setup window in the form of a straight line or a curved line. In this case, the ultrasound apparatus 100 may sense the drag input of the user and may move and display adjustment buttons on a plurality of slide bars to and on positions where the drag input is sensed.

FIG. 6 is an image which illustrates a gain line 630 which corresponds to gains, according to an exemplary embodiment.

The ultrasound apparatus 100 may obtain the gain line 630 which corresponds to gains which are set on a gain setup window 610, and may display the gain line 630 together with an ultrasound image 620.

For example, the ultrasound apparatus 100 may obtain the gain line 630 by connecting positions of adjustment buttons 611 on a plurality of slide bars (i.e., gains represented by the adjustment buttons 611). In this case, the ultrasound apparatus 100 may interpolate and calculate a gain between a first slide bar and a second slide bar by using a gain on the first slide bar and a gain on the second slide bar.

Further, if a user sets the gains by performing a drag operation on the gain setup window 610 in the form of a straight line or a curved line, the ultrasound apparatus 100 may obtain the gain line 630 based on corresponding dragged positions.

The ultrasound apparatus 100 may display the gain line 630 which corresponds to the gains which are set by the user on the gain setup window 610, adjacent to the ultrasound image 620 based on positions of depths of the ultrasound image 420, and thus may enable the user to intuitionally check, for example, a shape and/or a slope of the gain line 630.

Although FIG. 6 shows an example in which the gain line 630 is displayed on a right side of the ultrasound image 620, the gain line 630 is not limited thereto. In particular, the gain line 630 may be displayed on a bottom side, a top side, or a left side of the ultrasound image 620.

FIG. 7 is an image which illustrates a list 710 of preset gains, according to an exemplary embodiment.

As illustrated in FIG. 7, the ultrasound apparatus 100 may display the list 710 of one or more preset gains on a third area of a screen. The preset gain(s) may be previously set by a user or a system.

The list 710 of the preset gains may be displayed as images of gain lines which respectively correspond to the preset gains. In this case, the gain line may be variously displayed, for example, in the form of any one or more of a solid line, a dotted line, a dashed line, and/or a dotted and dashed line. The preset gain may be displayed in the form of an image which includes a plurality of slide bars.

The preset gains which are included in the list 710 may be automatically set by the ultrasound apparatus 100 or may be manually set by the user.

For example, the ultrasound apparatus 100 may extract and display typically and frequently used preset gains on the list 710, or may display preset gains selected by the user on the list 710.

The ultrasound apparatus 100 may extract a preset gain to be displayed on the third area of the screen based on at least one of probe setup information, application information, and object information. For example, if the user selects a 1D linear probe, the ultrasound apparatus 100 may extract a preset gain which is stored and mapped to the 1D linear probe and may display the extracted preset gain on the list 710. Further, if the user selects obstetrics (OB) from among a plurality of applications, the ultrasound apparatus 100 may extract a preset gain which relates to the application selected by the user and may display the extracted preset gain on the list 710.

The ultrasound apparatus 100 may further display at least one of a body marker, the application information, and the probe setup information on the list 710.

The application information refers to information which relates to a diagnosis department and/or a diagnosis site for ultrasound diagnosis. The diagnosis department may include any one or more of obstetrics (OB), gynecology (GYN), pediatrics (PD), chest surgery (CS), radiology (RD), neurosurgery (NS), abdomen, etc.

The body marker refers to a figure which represents a position or an object into which ultrasonic waves are scannable. Examples of the body marker may include any one or more of a liver shape, a heart shape, and a uterus shape. The probe setup information may refer to information which is set in relation to a probe which is configured for outputting an ultrasound signal. For example, when a low-frequency curved probe is used, low frequency convex′ may be further displayed in addition to a corresponding preset gain. If a high-frequency linear probe is used, ‘high frequency linear’ may be further displayed in addition to a corresponding preset gain.

The ultrasound apparatus 100 may receive a selection of one preset gain on the list 710. The ultrasound apparatus 100 may display the selected preset gain on a gain setup window, and may display, on a second area of a screen, an ultrasound image to which the selected preset gain is applied. In this case, the ultrasound apparatus 100 may receive an additional setup from the user in relation to the selected preset gain. In particular, the user may adjust the gain which is displayed on the gain setup window in detail by entirely or partially adjusting the displayed gain.

The ultrasound apparatus 100 enables the user to easily set a TGC value by providing a few types of preset TGC values.

The ultrasound apparatus 100 may provide an initialization button 720 for initializing the gain which is set on the gain setup window. If a touch input on the initialization button 720 is sensed, the ultrasound apparatus 100 may display an initial gain on the gain setup window and may display, on the second area of the screen, an ultrasound image to which the initial gain is applied.

FIG. 8 is a flowchart which illustrates a gain storing method which is executable by using the ultrasound apparatus 100, according to an exemplary embodiment.

In operation S810, the ultrasound apparatus 100 may receive, from a user, a request to store a gain which is set on a gain setup window. The user may transmit such a request by touching a certain icon which is displayed on a screen or by selecting a physical button.

In operation S820, the ultrasound apparatus 100 may store, in the memory 160, the gain which is set on the gain setup window. The ultrasound apparatus 100 may store the gain which is set on the gain setup window by mapping the gain to at least one of probe setup information and application information. In addition, the ultrasound apparatus 100 may store the gain which is set on the gain setup window by connecting the gain to at least one parameter which has previously been set in relation to an ultrasound image. A detailed description thereof will be provided below.

In operation S830, the ultrasound apparatus 100 may display an image of the stored gain in a third area. For example, if the user selects a save button, the ultrasound apparatus 100 may store, in the memory 160, a gain which is currently displayed on the gain setup window, and may display the gain which is currently displayed on the gain setup window on a list of preset gains. A detailed description thereof will be provided below with reference to FIG. 9.

FIGS. 9A, 9B, and 9C are images which illustrate a GUI which is configured for storing a gain, according to an exemplary embodiment.

As illustrated in FIG. 9A, the ultrasound apparatus 100 may output a save button 930 on a touchscreen. In this case, the ultrasound apparatus 100 may sense a touch input of a user on the save button 930. In this case, the ultrasound apparatus 100 enters a save mode.

As illustrated in FIG. 9B, when operating in the save mode, the ultrasound apparatus 100 may identifiably display an area (or a slot) for displaying a gain which is currently displayed on a gain setup window 910 on a list 940 of preset gains. For example, the ultrasound apparatus 100 may display a yellow frame around buttons 941, 942, and 943 for displaying images of the preset gains.

If a selection of the third button 943 is received from the user, as illustrated in FIG. 9C, the ultrasound apparatus 100 may store, in the memory 160, the gain which is currently displayed on the gain setup window 910, and may display, on the third button 943, an image of the gain which is currently displayed on the gain setup window 910.

Although FIG. 9C shows an example in which the image of the third button 943 is changed, according to an exemplary embodiment, the ultrasound apparatus 100 may newly generate a button for displaying the gain which is currently displayed on the gain setup window 910 and may further display the newly generated button next to the third button 943.

Accordingly, because the ultrasound apparatus 100 may display, on a certain button, a gain curve which corresponds to a current TGC value, the user may intuitionally check the stored TGC value (or a TGC line).

The ultrasound apparatus 100 may provide, on the touch screen, a close button 950 for closing a TGC setup mode. If a touch input of the user on the close button 950 is sensed, the ultrasound apparatus 100 may close the TGC setup mode.

According to another exemplary embodiment, if a touch input of the user is not sensed for a predetermined period of time, the ultrasound apparatus 100 may automatically close the TGC setup mode.

FIG. 10 is an image which illustrates a gain setup window for setting an LGC value, according to an exemplary embodiment.

Although a TGC value is described above as an example of a gain, the descriptions of the TGC value with respect to FIGS. 3 through 9 may also be applied to the LGC value.

As illustrated in FIG. 10, the ultrasound apparatus 100 may provide an LGC setup window on a touchscreen. For example, the ultrasound apparatus 100 may align a plurality of slide bars for setting LGC values in parallel in the LGC setup window.

In this case, a user may individually set each respective one of the LGC values by adjusting each of the slide bars, or may simultaneously set the LGC values by performing a drag operation in a direction which is perpendicular to the slide bars (a lateral direction) in the form of a straight line or a curved line.

The ultrasound apparatus 100 may display, on a screen in real time, an ultrasound image to which the LGC values set by the user are applied. In addition, the ultrasound apparatus 100 may store, in the memory 160, the LGC values which are set by the user, and may display a list of preset LGC values on the screen. A detailed description thereof is similar to the above description of the TGC value and thus is not provided here. Although the TGC setup window and the LGC setup window are displayed separately, the ultrasound apparatus 100 may also display the TGC setup window and the LGC setup window on the same screen.

FIG. 11 is a flowchart which illustrates an information providing method which is executable by using the ultrasound apparatus 100, according to another exemplary embodiment.

In operation S1110, the ultrasound apparatus 100 may display, on a screen, a list of preset gains. The list of the preset gains may be displayed as images of gain lines, or as numbers or text which represent the preset gains. A detailed description of the list of the preset gains is the same as the above description in relation to FIG. 7 and thus is not provided here.

The ultrasound apparatus 100 may extract one or more preset gains from the memory 160 or from a personalized server (e.g., a cloud server) and may form a list of the extracted preset gains. In particular, the ultrasound apparatus 100 may obtain a list of preset gains from any one or more of an external storage medium and/or an internal storage medium.

According to another exemplary embodiment, the ultrasound apparatus 100 may receive a list of preset gains from an external apparatus via wired and/or wireless communications.

In operation S1120, the ultrasound apparatus 100 may receive a selection of one preset gain which is included in the list. For example, the ultrasound apparatus 100 may sense a touch input (e.g., a tap gesture, a swipe gesture, or a flick gesture) or a voice command of a user in relation to one preset gain.

In operation S1130, the ultrasound apparatus 100 may apply the selected preset gain to ultrasound image data of an object. The ultrasound apparatus 100 may display, on the screen, an ultrasound image to which the selected preset gain is applied.

The ultrasound apparatus 100 may display, on a gain setup window, the preset gain which is selected by the user. For example, the ultrasound apparatus 100 may move at least one slide bar which is displayed on the gain setup window, based on the selected preset gain.

The ultrasound apparatus 100 may receive an additional setup from the user in relation to the preset gain which is displayed on the gain setup window. For example, the user may adjust the preset gain which is displayed on the gain setup window in detail by adjusting the slide bar which is displayed on the gain setup window.

The ultrasound apparatus 100 may store the gain which is additionally set by the user. In this case, the ultrasound apparatus 100 may store the gain which is additionally set by the user in at least one of an internal storage medium and/or an external storage medium (e.g., a universal serial bus (USB) memory or an optical disk).

In this case, the ultrasound apparatus 100 may further display, on the list of the preset gains, the gain which is stored in the internal storage medium and/or the external storage medium.

The ultrasound apparatus 100 may transmit the preset gain and/or the list of the preset gains to an external apparatus via wired and/or wireless communications. The external apparatus may be, but is not limited to, any one or more of a device of the user (e.g., a mobile phone, a smart phone, a laptop computer, a tablet PC, or an electric book device), another ultrasound apparatus, and/or a personalized server (e.g., a cloud server).

FIG. 12 is a flowchart which illustrates an information providing method which is executable by using the ultrasound apparatus 100, according to another exemplary embodiment.

In operation S1210, the ultrasound apparatus 100 may obtain ultrasound image data which relates to an object.

In operation S1220, the ultrasound apparatus 100 may display, on a first area of a screen, a gain setup window for setting a gain of the obtained ultrasound image data.

In operation S1230, the ultrasound apparatus 100 may display an ultrasound image of the object on a second area of the screen based on the obtained ultrasound image data.

In operation S1240, the ultrasound apparatus 100 may display a list of preset gains on a third area of the screen. The ultrasound apparatus 100 may obtain the list of the preset gains from an external storage medium.

The ultrasound apparatus 100 may receive a selection of one preset gain from among the preset gains included in the list. The ultrasound apparatus 100 may display the selected preset gain on the gain setup window, and may display, on the second area of the screen, an ultrasound image to which the selected preset gain is applied.

For example, as illustrated in FIG. 9A, the ultrasound apparatus 100 may display the gain setup window 910, an ultrasound image 920, and the list 940 of the preset gains on one screen. In this case, a user may set a TGC value and/or an LGC value by directly adjusting slide bars which are displayed on the gain setup window 910, or may select one preset gain (e.g., item 943 of FIG. 9B) from among the preset gains which are displayed on the list 940.

If the user selects one preset gain (e.g., item 943) from among the preset gains which are displayed on the list 940, the ultrasound apparatus 100 may display the selected preset gain (e.g., item 943) on the gain setup window 910. The ultrasound apparatus 100 may receive an additional setup from the user in relation to the preset gain which is displayed on the gain setup window 910. The ultrasound apparatus 100 may store, in the memory 160 and/or in an external storage medium, the gain which is additionally set on the gain setup window 910, and may display an image of the stored gain on the list 940 of the preset gains.

The ultrasound apparatus 100 may display at least one parameter which is mapped to the selected preset gain (e.g., item 943). According to another exemplary embodiment, the ultrasound apparatus 100 may determine at least one parameter which is mapped to the selected preset gain (e.g., item 943) and may apply the determined parameter to a system. In particular, the ultrasound apparatus 100 may change the setup of an ultrasound system based on at least one parameter which is mapped to the selected preset gain (e.g., item 943). A detailed description thereof will be provided below with reference to FIGS. 13, 14, 15, 16, and 17.

FIG. 13 is a table which shows setup parameters which relate to an ultrasound image, according to an exemplary embodiment.

As illustrated in FIG. 13, the setup parameters which relate to the ultrasound image may include at least one of frequency 1305, dynamic range 1310, frame average 1315, reject level 1320, gray map 1325, spatial compound 1330, dynamic magnetic resonance (DMR+) 1335, harmonic 1340, scan area 1345, edge enhance 1350, speed 1355, power 1360, line density 1365, full spectrum image (FSI) 1370, focus number 1375, gain 1380, and depth 1385.

The frequency 1305 refers to a parameter which relates to changing a transmission or reception frequency which is applied to a probe. For example, a user may set the frequency 1305 by selecting one of Pen, Gen, and Res.

The dynamic range 1310 is a parameter which relates to adjusting brightness by changing a ratio of a minimum value and a maximum value of an input signal. For example, the user may set the dynamic range 1310 by selecting a value between 50 and 200.

The frame average 1315 is a parameter which relates to reducing random noise of the ultrasound image. For example, the user may set the frame average 1315 by selecting a value between 0 and 15.

The reject level 1320 is a parameter which relates to reducing noise of the ultrasound image. For example, the user may set the reject level 1320 by selecting a value between 1 and 32.

The gray map 1325 is a parameter which relates to determining a gray scale by changing a post curve of the ultrasound image. For example, the user may set the gray map 1325 by selecting a value between 1 and 13. A detailed description thereof will be provided below with reference to FIG. 16.

The spatial compound 1330 is a parameter which relates to adjusting a density of the ultrasound image. For example, the user may set the spatial compound 1330 by selecting one of low, medium, and high.

The DMR+ 1335 is a parameter which relates to post-processing of the ultrasound image and is a parameter which relates to reducing noise and enhancing edges. For example, the user may set the DMR+ 1335 by selecting a value between 1 and 5.

The harmonic 1340 is a parameter which relates to optimizing the ultrasound image by using a high frequency. For example, the user may set the harmonic 1340 by selecting one of on and off.

The scan area 1345 is a parameter which relates to adjusting a horizontal width (%) of the ultrasound image. For example, the user may set the scan area 1345 by selecting a value between 40 and 100.

The edge enhance 1350 is a parameter which relates to sharpening edges of images of tissues or organs. For example, the user may set the edge enhance 1350 by selecting a value between −3 and 3.

The speed 1355 is a parameter which relates to increasing a resolution by adjusting a speed of tissues. For example, the user may set the speed 1355 by selecting a value between 1440 and 1620 m/s.

The power 1360 is a parameter which relates to selecting an intensity of an ultrasonic output. For example, the user may set the power 1360 by selecting a value between 10 and 100.

The line density 1365 is a parameter which relates to adjusting a density of the ultrasound image. For example, the user may set the line density 1365 by selecting one of low, mid1, mid2, and high.

The FSI 1370 is a parameter which relates to adjusting a ratio of mixing frequencies. For example, the user may set the FSI 1370 by selecting a value between 1 and 3.

The focus number 1375 is a parameter which relates to setting positions and a number of focuses. For example, the user may set the focus number 1375 by selecting a value between 1 and 4.

The gain 1380 is a parameter which relates to adjusting a brightness of the ultrasound image. For example, the user may set the gain 1380 by selecting a value between 1 and 100.

The depth 1385 is a parameter which relates to adjusting a depth of the ultrasound image to be scanned. The depth 1385 may vary based on the type of a probe which is used with respect to the image. For example, with respect to a convex probe, the user may set the depth 1385 by selecting a value between 6 and 30 cm.

FIGS. 14A and 14B are images which illustrate a GUI which is configured for setting parameters which relate to an ultrasound image, according to an exemplary embodiment.

The ultrasound apparatus 100 may provide a setup window 1400 which is configured for enabling a user to individually set the parameters which relate to the ultrasound image.

For example, as illustrated in FIG. 14A, the ultrasound apparatus 100 may provide, on a screen, the setup window 1400 for setting parameters such as the frequency 1305, the dynamic range 1310, the frame average 1315, the reject level 1320, the gray map 1325, the DMR+ 1335, the harmonic 1340, the speed 1355, and the FSI 1370.

Further, as illustrated in FIG. 14B, the ultrasound apparatus 100 may provide the setup window 1400 for setting parameters such as the scan area 1345, the edge enhance 1350, the power 1360, and the line density 1365.

The ultrasound apparatus 100 may sense a parameter which is input (or selected) by a user on the setup window 1400. The ultrasound apparatus 100 may store the input (or selected) parameter in response to a request of the user to store the parameter. A detailed description thereof will be provided below with reference to FIG. 15.

FIGS. 15A, 15B, 15C, and 15D are images which illustrate a GUI which is configured for enabling a user to store at least one preset parameter, according to an exemplary embodiment.

As illustrated in FIG. 15A and FIG. 15B, if a user touches a certain icon on the touchscreen 131 or selects a certain button on the control panel 132, the ultrasound apparatus 100 may provide a GUI 1500 for storing a parameter which is set by the user.

For example, if a selection of a probe button 1510 by the user is sensed, the ultrasound apparatus 100 may provide, on the touchscreen 131, the GUI 1500 for adjusting a gain or at least one parameter which relates to an ultrasound image.

As illustrated in FIG. 15B, the ultrasound apparatus 100 may display, on a predetermined area of the GUI 1500, a probe list 1520 which includes identification information which relates to one or more probes which are connected to the ultrasound apparatus 100. For example, if a probe 1 C2-8, a probe 2 L5-13, and a probe 3 VE4-8 are connected to the ultrasound apparatus 100, the ultrasound apparatus 100 may display identification information which relates to each of the probe 1 C2-8, the probe 2 L5-13, and the probe 3 VE4-8 on the probe list 1520. Identification information which relates to a probe is information which may be used for identifying the probe and may include, for example, any one or more of a probe image, a probe name, and a probe type.

The ultrasound apparatus 100 may sense a selection of at least one probe from the probe list 1520 by the user. For example, the user may select the probe 3 VE4-8 from the probe list 1520.

In addition, the ultrasound apparatus 100 may display a list 1530 of applications (e.g., diagnosis departments) on the predetermined area of the GUI 1500 and may receive a selection of an application from the list 1530 by the user. For example, the user may select “Abdomen” from the list 1530 of the applications.

In this case, the ultrasound apparatus 100 may display a list of presets which correspond to the probe 3 VE4-8 which is selected by the user. Further, according to another exemplary embodiment, the ultrasound apparatus 100 may display a list of presets which correspond to the probe 3 VE4-8 and the application (e.g., “Abdomen”) which are selected by the user. In this case, the list of the presets may include system presets which include parameters which are previously set by a system and are unchangeable, and user presets which include parameters which are arbitrarily set by the user.

The ultrasound apparatus 100 may provide, on the GUI 1500, a default area 1540 for displaying the system presets which are mapped to the parameters which are previously set by the system and are unchangeable, and an arbitrary area 1550 for displaying the user presets which are mapped to the parameters which are arbitrarily set by the user.

If the user selects one preset item (e.g., “fetal heart”) from the list of the presets which respectively correspond to at least one of the probe and the application and then touches a predetermined button 1560, the ultrasound apparatus 100 may provide preset parameters which correspond to the selected preset item (i.e., “fetal heart”).

For example, as illustrated in FIG. 15C, the ultrasound apparatus 100 may display preset parameters which respectively correspond to each of the frequency 1305, the frame average 1315, the gray map 1325, the harmonic 1340, the line density 1365, and the focus number 1375 which are mapped to the selected preset item (i.e., “fetal heart”). In this case, the user may generate a new user preset by changing the parameters which are displayed on a screen. The newly generated user preset may be displayed on the arbitrary area 1550. In this case, the user may set a name of the newly generated user preset.

For example, a first user may generate a user preset named ‘user1’ and may store a plurality of parameters which are set by the first user by mapping the parameters to ‘user1’. In addition, a second user may store a plurality of parameters which are set by the second user by mapping these parameters to a user preset named ‘user2’. If a third user sets parameters in relation to a face of a fetus (i.e., a different selected preset item), the third user may store the parameters which are set in relation to the face of the fetus by mapping these parameters to a user preset named ‘Face’.

Further, the user may set a gain and may generate a new user preset by adding the set gain. For example, if the user touches a TGC button on the screen, the ultrasound apparatus 100 may provide a setup window for setting the gain (e.g., a TGC value).

As illustrated in FIG. 15D, the ultrasound apparatus 100 may provide a gain setup window and may receive a gain which is set by the user on the gain setup window. A method thereof is described in detail above and thus is not described here.

If the ultrasound apparatus 100 receives, from the user, a request to store the set gain, the ultrasound apparatus 100 may generate a user preset which includes the set gain. In this case, the gain which is set by the user may be mapped to at least one of a probe (e.g., the probe 3) and application information (e.g., Abdomen) which are selected by the user and may be stored as a user preset. The gain which is set by the user may be stored as a user preset in the arbitrary area 1560 together with preset parameters. Accordingly, the ultrasound apparatus 100 enables the user to make a frequently-used TGC line for each probe and to store the TGC line as a user preset. For example, the user may store a TGC line which is frequently used for a carotid ultrasound image by mapping this TGC line to a probe which is used for generating the carotid ultrasound image. In this case, the ultrasound apparatus 100 may generate a preset mapping table which includes the identification information which relates to the probes, the parameters which relate to the ultrasound image, and the gains, which are mapped to each other, and may store the preset mapping table in the memory 160.

Although FIGS. 15A, 15B, 15C, and 15D show an example when a probe and an application are selected first and then a parameter is adjusted or a TGC value is set, according to an exemplary embodiment, the parameter or the TGC value may be set first and then the probe or the application may be selected and connected to the set parameter or the TGC value.

A method for automatically extracting a gain which is stored and mapped to a probe and applying the gain to a system by the ultrasound apparatus 100 will now be described.

FIG. 16 is a flowchart which illustrates an information providing method which is executable by using the ultrasound apparatus 100 based on identification information of a probe, according to an exemplary embodiment.

In operation S1610, the ultrasound apparatus 100 may determine identification information which relates to a probe which is connected to the ultrasound apparatus 100. For example, the ultrasound apparatus 100 may determine identification information which relates to a probe which is connected to the ultrasound apparatus 100, for example, a probe image, a probe name, and a probe type, by receiving the identification information which relates to the connected probe which is stored in the memory 160.

If a plurality of probes are connected to the ultrasound apparatus 100, the ultrasound apparatus 100 may determine identification information which relates to each of the probes and may display a probe list which includes the identification information which relates to each of the probes.

In operation S1620, the ultrasound apparatus 100 may extract a preset gain which corresponds to the identification information which relates to the probe. For example, the ultrasound apparatus 100 may extract, from a preset mapping table, a preset gain which is mapped to the identification information which relates the probe based on the identification information which relates to the probe.

The ultrasound apparatus 100 may receive a selection of identification information which relates to one probe on the probe list, which probe list includes the identification information which relates to each of the probes which are connected to the ultrasound apparatus 100. In this case, the ultrasound apparatus 100 may extract a preset gain which corresponds to the identification information which relates to the selected probe.
